ANcHoRlNG APPARATUS Filed July '13l 1925 Y U 77 z'v tps y urPatentdlFeb.4.1950 n n ANCHO'RING `venient andfsatisfactor'y' for use whereverVfound applicable.' A particular object of the;

invention is to provide improved anchoring f' apparatus whichA can beproperly secured in f a wall or ceiling in a minimum amount of. v

' siredsize and form, but which in this instance' is 'tubular andisprovidedwith drill teeth 11.

Atime,V the apparatusgbeing vassembledv while it is being installed. Y 1i In'one embodiment of vthe invention, an

v anchor shell havingdrill teeth at one end v and a taper seat at theother end is seated "lform a cylindrical hole therein. The shell is thenwithdrawn from the cylindrical "holeff andfa tapered'lplug is insertedin the drilling end thereof, after which'it is 'again driven.' into'thehole tofbe 'expanded therein. The n y with ajchuck 1,8 which is providedwithV av tapered recess 19 adaptedfto accommodate chuck isthenremoved-from the tapered endy ing an aperture therethrough is positionedupon the taper seat formed on the shell. The chuck is then employedtodrive the collar ory ceiling plate on thefshell until it is rmly` seatedthereon. 1 Many other objects 'and advantages of the' constructionherein shownan'd described will Tao disclosure herein given'.
